SEM 45508 Black Rust Trap

This is some really GOOD stuff I used it to reseal a metal header over an outside door. The header had 30 years of latex paint and rust developing on it. I sanded it off using a 4" grinder and sanding pad. I was amazed at how easy the rust seal flowed on and adhered to the metal overhead. It hardened quickly over night and left a high glossy, almost like glass, surface. I got a lot on my hands, as I did not use gloves and painting overhead. It would not come off my hands for a week. Further proof of how good this stuff is. Next time I will use gloves : )

This is the best undercoating you can use on a new or old car to protect it from rusting!

Works like a charm. Don't get it on bare hands. Even works on aluminum.
